2015-09-09stdlib: Fix bug with unicode detection in reShane Howley
Fix bug with unrecognised 'unicode' option in re:split/2,3 & re:replace/3,4 when using pre-compiled regex.

2014-02-12[stdlib] Remove a confusing comment in the re moduleHans Bolinder
The line %-opaque mp() :: {re_pattern, _, _, _, _}. has been removed. The mp() tuple is called 'opaque' in re(3), but it is not an opaque type. The out-commented -opaque declaration was confusing.
2013-08-09Add match_limit and match_limit_recursion optionsPatrik Nyblom
Added to re:run and sets the corresponding fields in 'extra' struct for the PCRE match engine. The result can be viewed by also setting 'report_errors' when matching. Some housekeeping was also done... The offset option also did not properly check for offset's >= 0. Change nomatch to BADARG when pre-compiled mp() is faked: By constructing a 5-tuple with faked content but the right data types, you could do a re:run which returned nomatch when in fact the mp() was bad. The cheapest solution is to check the return from pcre_exec better. Remove unreachable code in erts_bif_re.c: Replaced tests for things that logically simply cannot happen with ASSERT.

2013-08-09Add documentation of extensions to re modulePatrik Nyblom
The following compile options are documented: no_start_optimize ucp never_utf The following run options are documented: notempty_atstart {capture, all_names} The following new functions are documented: re:inspect/2
2013-08-09Add new options to Erlang re interface and mend dupnamesPatrik Nyblom
Add notempty_atstart, no_start_optimize, ucp and never_utf options from new PCRE version. Use the new notempty_atstart in global matching. Add inspect/2 function Correctly handle dupnames when capturing a name, as in Perl, get the leftmost matching occurence. Also added all_names, to get all the names in the pattern in alphabetical (name) order. To be able to use this in global matching, an inspect function that can dig out a namelist was added.

2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.

* rb/stdlib_re_unicode_fixes: Fix lost unicode option in re:compile() Refactor out repeated block in re module Fix re:replace/4 to handle unicode charlist Replacement argument Fix re:replace/4 to handle unicode charlist RE argument Fix re:replace/4 to handle binary unicode output when nothing replaced OTP-8394 A number of bugs concerning re and unicode are corrected: - re:compile no longer loses unicode option, which also fixes bug in re:split. - re:replace now handles unicode charlist replacement argument - re:replace now handles unicode RE charlist argument correctly - re:replace now handles binary unicode output correctly when nothing is replaced. Most code, testcases and error isolation done by Rory Byrne.

2010-01-27Fix re:replace/4 to handle unicode charlist Replacement argumentRory Byrne
A bug in re:replace/4 causes a badarg exception to be thrown when the Replacement argument is a charlist containing non-ascii codepoints. The problem is that the code incorrectly assumes that the Replacement text is iodata() and calls iolist_to_binary/1 on it. This patch fixes it to obey the 'unicode' option and handle charlist() Replacement arguments correctly.
2010-01-27Fix re:replace/4 to handle binary unicode output when nothing replacedRory Byrne
A bug with re:replace/4 causes an exception when: (a) it's given a unicode charlist as input; (b) it's set to {return,binary}; and (c) it finds nothing to replace. The problem is: when re:replace/4 does not find anything to replace in its Subject input, it calls iolist_to_binary on this data. This fails if the original input is a charlist with non-ascii codepoints.
